The 3-inch ordnance rifle was mounted on the standard carriage for the 6-pounder field gun. Because its projectile was heavier than a 6-pound shot, the 3-inch rifle's greater recoil sometimes caused damage to the trail or the cheek pieces of the carriage. [17] The 6-pounder carriage weighed 900 lb (408 kg). [18]

The 3-inch gun M1917 was a World War I-era US-made anti-aircraft gun based on the 3-inch gun M1903. It was designed for a fixed mounting and remained in service, primarily at Coast Artillery installations, through World War II .
3.8-inch Gun, Models of 1904 and 1907 Similar to the 3-inch gun, but scaled up with a significantly longer barrel - 111.25 inches (2.826 m) overall gun body length instead of 87.8 inches (2.23 m) - in a larger caliber, with a lengthened recoil - 58.5 inches (1.49 m) instead of 45 inches (1.1 m) - as well as with a different extractor.
Sholes chose the size of the keys to be on three-quarter [3 ⁄ 4, or 0.75] inch centers (about 19 mm, versus musical piano keys which are 23.5 mm or about 0.93 inches wide). 0.75 inches has turned out to be optimum for fast key entry by the average-size hand, and keyboards with this key size are called "full-sized keyboards".
Modern keyboard models contain a set number of total keys according to their given standard, described as 101, 104, 105, etc. and sold as "Full-size" keyboards. [8] Modern keyboards matching US conventions typically have 104 keys while the 105 key layout is the norm in the rest of the world.
The 3-inch round was chosen because it was the smallest caliber ammunition that could be fitted with a VT radar proximity fuze. The twin barrel mount was believed to be more effective against faster aircraft and guided missiles than the single mounted 5"/54 caliber Mark 42 gun , hence, the single barrel version of the Mark 26 never saw service use.
The 3-inch/23-caliber gun (spoken "three-inch-twenty-three-caliber") was the standard anti-aircraft gun for United States destroyers through World War I and the 1920s. United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 23 calibers long (barrel length is 3" × 23 = 69" or 1.75 meters.) [1]
